Calculation of UNil for the cyclic group of order two
Abstract
Cappell's unitary nilpotent groups UNil(R;R,R) are calculated for the integral group ring R=Z[C2] of the cyclic group C2 of order two. Specifically, they are determined as modules over the Verschiebung algebra V using the Connolly--Ranicki isomorphism and the Connolly--Davis relations.
